Odorless waste disposer unit

ABSTRACT

A device for grinding and reducing food waste to be disposed of in sewage systems. The device eliminates disagreeable odours by flooding the grinding chamber with water using a swivel plug that retains a gap of fresh water from the last use of the tap. The fresh water serves as a barrier to odors by creating a partition, isolating the dirty water in the grinding chamber. The matter to be grinded is segmented and torn up several times by a grinding apparatus made of cutting blades while it swirls in the water until it is reduced to particles small enough to pass through openings in a spherical grid. The device can be adapted to different uses: residential, commercial or industrial.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a divisional of application Ser. No. 14/967,277 the title of which is Floating methanation system.

BACKGROUND OF THE INVENTION

The invention is in the technical field of waste disposer units, specifically in the field of mechanisms for reducing food waste.

Usually, when a waste disposer unit is installed, food waste is fed with water into this waste disposer unit stored under a kitchen sink. The food waste is grinded within the disposer in order to reduce it so that it can be flushed to the plumbing system of a residence or commercial establishment.

One of the problems that seem related to the current state of technology in this domain is the odor emanating.

SUMMARY OF THE INVENTION

The waste disposer unit claimed in this application addresses the problem of odor emanating from the sink by flooding the grinding chamber with water and using a swivel plug that allows the retention of water in the grinding chamber and creates a partition with clear water from the tap to isolate dirty water remaining in the grinding chamber.

The proposed unit has a grinding apparatus made of cutting blades, placed in front of a spherical grid, that segment the matter by tearing it up several times while it swirls in the water. The spherical grid serves as a barrier preventing large objects from going through.

DESCRIPTION OF THE INVENTION

Referring to the drawings in greater detail and by reference characters thereto, there is illustrated an odorless waste disposer unit 300.

In order to prevent the proliferation and emanation of disagreeable odors and to achieve the odorless grinding of waste material, the principle consists of the retention of water flooding the chopping chamber 301, establishing a ring of clean water around a swivel plug 302 from the ultimate flow of the tap. The swivel plug 302 allows the creation of a partition with clear water from the tap serving to isolate the dirty water remaining in the grinding chamber. These elements are illustrated in FIGS. 17A and 17C.

The siphon that maintains the water level is equipped with a bypass valve 303 (seen in FIG. 17B) that allows complete drainage when maintenance is required. The swivel plug 302 can be tilted and removed (seen in FIG. 17C) to facilitate the passing through of large pieces of waste. A sealing cover plug 304 (FIG. 17D) can be added over when one wishes to fill the sink.

A float 305 (shown in FIG. 17C) can be used to activate the mechanism when water accumulates in the sink. Because the chopping elements in the grinding chamber 301 make a fence, holding the not yet chopped matter against it, the water flowing from the tap may then rise in level and lift the float 305 that will engage the grinding motion to reduce that matter. When the matter has been evacuated from the grinding chamber 301, the water will be free to rest to its proper level, relieving the contact from the float and stopping the motion. In this way, we have an automation potential.

The waste disposer unit segments the objects by slicing them, or by tearing them up several times while they swirl in the water inside the chopping chamber 301. This process of cutting and tearing continues until the matter is reduced to fragments small enough to go through the openings in a spherical grid 306 (shown in FIG. 17H and FIG. 17I).

Behind the spherical grid 306, there may be one or several back blades 307 (seen in FIG. 17I); their cutting edges segment the particles coming through the openings of the grid 306. The tail edges of the blades 307 rise apart as a propeller pitch to create a vortex to pump the material when necessary.

This waste disposer unit can be fabricated in different sizes and adapted to commercial and industrial uses. A few possible embodiments are illustrated in FIGS. 17E, 17F, and 17G.

As can be seen in FIG. 17E, the waste disposer unit can be installed inside a recipient big enough to contain large solid matter to be grinded. Since these large objects swirl in the recipient by the impact, the turbulence and the vortex coming from the rotation of the back blades 307, they can be torn up and shredded into particles.

FIG. 17G shows another possible embodiment for industrial use. In this case, the invention can be used to extract decanted layers of sediments.

It will be understood that the above described embodiments are for purposes of illustration only, and that changes or modifications may be made thereto without departing from the spirit and scope of the invention.
